INFRASTRUCTURE VERSION - IT'S OUT!!!
I am sitting at the airport and posting this from my laptop that is hooked up to the latest download. It shows up as "Security Enabled WPA2 Network" on my laptop (XP SP3). Prior to the update it showed up as ad-hoc.
I don't have a 4g signal here at Nashville airport, so I am just using 3g. I will play with 4g when I get home (DFW).
